摘　　要：报道了一种使用多光纤耦合及光学多道分析器实现多对象光谱同时实时采集的方法和装置。利用该装置成功地采集了单对象、3对象和 5对象光谱。空间分辨率达到 0 5mm ,光谱探测范围 2 0 0～ 110 0nm ,使用OMA 4系统 ,在 1cm2 的象面上最多可采集对象达 2 0。为了保证该装置充分利用光能 ,又尽量减小对光谱仪分辨率的影响 ,对所使用的耦合透镜的光路设计进行了探讨。该装置在光束传输中的质量监控以及在光谱时间、空间分辨测量中可得到广泛的应用。A new kind of instrument and method for simultaneous and real-time collection of multi-object spectra by using multi-fiber coupling and Optical Multi-channel Analysis(OMA) was reported. The spectral signals of one object, three objects and five objects were collected successfully in experiments. The spacial resolution of 0.5 mm and detected spectral range of 200-1 100 nm were reached, and at most twenty objects could be collected on the image plane of 1 cm 2 area with OMA 4 system. The design of the coupling lens's light path was discussed to guarantee enough light energy to enter the instrument and little effect on the resolution of spectral instrument. The instrument can be applied widely to the areas of supervising and controlling the quality of light beam in transmission and in the time-resolved and spatial-resolved spectral measurement.
